BACKGROUND OF THE INVENTION

This invention relates to an attachment for use with a handheldjackhammer to mechanically dig a trench into the ground.

Digging a trench into the ground can be a very labor intensive job usinga shovel and pick. It would be beneficial to have a device that could beused with a handheld jackhammer to dig a trench of your required widthfor your job application.

Said device would, with the use of a handheld jackhammer, dig out“plugs” of dirt, leaving a trench in the ground. Other devices thatwould be able to dig a trench are very large and unable to be operatedin small spaces such as a basement. Therefore, being handheld andportable would be an advantage in many applications.

Various types of handheld jackhammer attachments are known in the art.Typical of these devises is the “Stake/Post Driver for Use With HandheldJackhammer” is detailed n U.S. Pat. No. 6,347,672, dated Feb. 19, 2002,to Patrick Reardon. The device is a hammer assembly including a hammerelement configured to strike the upper portion of the stake or postcoupled to the handheld Jackhammer to mechanically drive a stake or postinto the ground. This devise does not have the capability to dig atrench to install piping under the ground.

An object of this invention is to provide a new and improved trenchingjackhammer attachment which is capable of digging out “plugs” of dirt,leaving a trench in the ground.

Another object of the invention is to provide a new and improvedtrenching jackhammer attachment in which the “plugs” of dirt can beeasily lifted out of the hole and later replaced if needed. This wouldenable faster, easier trenching, especially when grass covered “plugs”can be replaced to eliminate the need for new seeding over work area.

BRIEF SUMMARY OF THE INVENTION

These and other objects of the invention are provided in a new andimproved trenching jackhammer attachment which includes a preferredembodiment, a rear panel with sharpened teeth to cut into the ground,two side panels also with sharpened teeth and a shaft attached to therear panel by which the trenching jackhammer attachment is attached to ahandheld jackhammer.

BRIEF DESCRIPTION OF THE SEVERAL VIEW OF THE DRAWING

The following detailed description illustrates the invention by way ofexample and not by way of limitation. This description will clearlyenable one skilled in the art to make and use the invention.

Referring to Figs. I and II of the drawings, a preferred embodiment ofthe trenching jackhammer attachment is generally illustrated byreference numeral 1. The trenching jackhammer attachment 1 is comprisedof a rear panel 2 made with sharpened teeth to cut into the ground; and2 side panels 3 and 4 also with sharpened teeth. Said rear panel 2 andside panels 3 and 4 are attached at right angles to each other. A shaft5 is attached to rear panel 2 by which the trenching jackhammerattachment is attached to a handheld jackhammer.

It will be appreciated by those skilled in this area that the trenchingjackhammer attachment offers a practical, portable and efficient devicefor digging a trench in the ground. This devise could be used in manyapplications, including but not limited to, trenching for new houseplumbing in basement, trenching for electrical lines, cable line andirrigation systems. This devise is also applicable for all other typesof work where trenching is needed.

As various changes could be made in the above constructions withoutdeparting from the scope of the invention, it is intended that allmatter contained in the above description or shown in the accompanyingdrawings shall be interpreted as illustrative and not in a limitingsense.

It is also understood that the contained descriptions are intended tocover all of the generic and specific features of the invention hereindescribed, and all statements of the scope of the invention, which, as amatter of language, might be said to fall there between.

1. A trenching jackhammer attachment, for use with a handheldjackhammer, to mechanically dig a trench into the ground.
 2. A trenchingjackhammer attachment of claim 1 comprising of a rear panel, 2 sidepanels attached at right angles to the rear panel and a shaft attachedto the rear panel.
 3. A trenching jackhammer attachment of claim 1 wheresaid rear panel is made with sharpened teeth to enable it to cut intothe ground.
 4. A trenching jackhammer attachment of claim 1 where saidside panels, also made with sharpened teeth, are attached at rightangles to the rear panel.
 5. A trenching jackhammer attachment of claim1 where said shaft if attached to the rear panel by which the trenchingjackhammer attachment is attached to a handheld jackhammer.
 6. Atrenching jackhammer attachment of claim 1 where said trenchingjackhammer attachment is attached at a handheld jackhammer enable theoperator to mechanically dig out “plugs” of dirt, leaving a trench inthe ground.
